Specification of Letters Patent.

Application filed September 29, mos. Serial m. 455,368.

To all whom it may concern;

Be it known that I, ELMER ENGEBRETSON, a citizen of the United States, residing at Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Im rovcments in A paratuses for Producing ilniform Fluidressure for Engines, of which the following is a specification, reference being had therein to t e accompanying drawing.

This invention relates to an apparatus or mechanism for roducing fluid pressure composed of explo ed gasolene an air for actuating engines, and the primary object of the same is to store energy resulting from the explosion of a proper mixture of air and gasoene under a predetermined pressure and feed it regularly and uniformly to an engine and avoid the fluctuations or irregular strokes existing in ordinary gasolene engines due to irregularit of explosions.

To the accomp ishment of the recited object and others coordinate therewith, the preferred embodiment of the invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and embraced within the scope of the appended claims.

In the drawings :Figure I is a sectional elevation of an apparatus embodying the features of the invention. Fig. II is a longitudinal section, partially in side elevation, of a portion of the apparatus. Fig. III is a horizontal section on the line 33' of Fig. I. Fig. IV is a transverse vertical section on the line 44 of Fig. I. Fig. V is a horizontal section taken in the plane of the line 5-5 of Fi I, showin the air compressors'in plan.

The numerai 5 designates what may be generally termed a compressing gasometer, and comprises an upright cylinder (6) with o 11 top and supported by a base (7) ane ored or secured by any suitable means to a support as shown. Over this cylinder (6) a she or casing (8) is movably mounted to have vertical movement and is similar to a .gasometer shell or bell with theexception and maintain inthe cylinder a given temporarily stored pressure that will not obstruct incoming pressure charges, due to successive explosions carried on, in another part of the apparatus as 'wil-l be prcsentlyexplained. The shell or casing (8) will move vertically on the chamber (6), as hereinbefore stated, and excessive impulses affecting the interior of the com ressing gasometer will cause the said shel or casing to appreciably rise and fall and automatically check or control the flow or sup ly of gasolene to the explosive medium. 0 prevent leakage, the lower extremity of the shell or casing (8) is provided with a packing or gasket (10) cooperatingwith .the base (7 and the cylinder (6). The shell or casing (8) is also provided with a lug (1 1) movably engaging a rod or trip (12) having an upper headed end (13), and between the latter and said lug a spring (14) surrounds and operates to restore t erod to normal position when free from the restraint of the casing or shell (8). The rod or trip (12) projects below the support for the compressing gasometer and is connected to one arm of a bell-crank lever (15) sup orted by a hanger (16), the remaining bel -crank arm being connected by a rod (17) and lever (18) with a plug valve (19) in a feed pipe (20.) from a gasolene tank or supply reservoir (21), preferably suspended as shown.

The pipe (20) leads upwardly at'an incline to and connects with a pump (22) having a piston (23) o eratively associated with a shaft (24). he lower extremity of the pump body is fitted in the upper portion of a combustion chamber (25) having exterior ribs (26) and intervening channels (27) to cool it and at the same time preserve the necessary strength. This combustion chamber will be provided with any suitable form of approved s arkingplugs and attachments conventiona ly shown, as at 28, and which will be under operative control of the engine. To one end 0 the combustion chamber twin compressors (29) and (30) are connected, the one compressor (29) being fed by a pipe (31) leading to the atmosphere, and communicating with the other compressor (30) by a suitable valve port (32), the latter compressor being directly connected to the combustion chamber by a pipe (33) having a suitable check valve therein. Both compressors (29) and (30) are provided with pistons (34) and (35), res ectively, connected up to cranks (36) and (37 of the shaft (24) and having alternate Patented June 22, 1909.

reverse reci rocations imparted thereto so that while t wolpiston (34) 18 conpressing, the

piston (35) be rising and on return will compress and closocommunication through the valvedport (32) with compressor (29) and 0 on communication with the combustion 0 amber (25) through valved pipe (33). By this means air will be forced under pressure into the combustion chamber (25) The air-in the combustion chamber (25) will commingle with the gasolene fed into said chamber in predetermined quantities by the pump (22) and under the control of the valve (19), and at re lar and r0 erly timed intervals the spar ing plu $28 wil ignite the successive charges in t e combustion chamber. The shaft (24) is supported on the combustion chamber (25) by an upright (38) and also by an upright (38 and is provided with a hand wheel (39) for initial starting 0 erations. The shaft (24) may be connecte by a suitable lever operated clutch (40) and gear (41) with a gear (42) on a shaft (43) running to the engine so that the shaft (24) may be regularl run from the engine after the latter is fu ly started andworks regularl As before indicated the mechanism wil .be initially started or actuated in the event that the engine runs down or from some cause ceases to operate by manually rotatin the wheel and at which time the gear (41) wi lbe disconnected from the gear (42.) After the generating mechanism starts, the said gear (41) is thrown into mesh with the gear (42)v and the explosion and storage of the energy will continue and feed to the motor regu arly ensue. p

The potential energy generated in the combustion chamber (25) passes out through a suitably valved pipe (44) connected to the end thereof opposite that with which the compressor (30) communicates, the said ipe (44) o ening at its op osite end into the ottom 0 the cylinder 6) and constitutes the feed means for said cylinder. The outlet of the cylinder (6) consists of a pipe (45) extending u wardly thereinto and having an upper croo ed extremity (46) below the open to of the cylinder. The pi e (45) continues be ow the base (7) of t e cylinder (6) throu h which it passes to and communicates with t e bottom of a storage reservoir (47 and operatively associated with said ipe are two pressure gages (48) and (49). T e index (50) of the gage (48) has a toothed disk or wheel (51) ecured to or forming part of the inner end thereof, and with said disk or wheel (51) a toothed segment (52) is held in continual mesh and carried on the end of an angle arm (53) operatively connected to a controlling arm (54) carrying a worm (55) and connected to a reducing valve casing (56) to have a swin ing movement. The worm (55) meshes wit 1 a Worm gear (57) secured to the stem (58) of a reducing valve plug (59) having increase or decrease the passage throug the valve and regulate or reduce the pressure of the fluid flowing through the pipe (45) and which ressure will be constant in accordance a suitable opening therethro h to with t e'setting or adjustment of the gage (48); The pipe (45).adjacent the reservoir (47) also has a reduci valve (60) in all resfirects similar to'that ust described and in l' e manner controlled by the gage (49). These reducing valves provide for storage of the fluid under uniform pressure in the reservoir (47 in accordance with a predetermined calculation and which may be varied at will.

From the bottom of the reservoir (47) a small pipe (61) leads to the top of the gasolene reservoir or tank (21), and said pipe is provided with a suitable" cut-off valve (62) whereby, if desired, pressure from the reservoir (47) may be fed to the reservoir or tank (21) to assist inforcing or feedin the gasolene upwardly to the-pump (22 To the center of the top of the reservoir (47 a supply pipe (63) is attached andleads to the cylmder of the en ine, and this supply pipe has a suitable cut-ofl valve (64) to control the flow of the fluid to the engine.

From the foregoing the operation will be understood, and briefly stated, the primal fluid pressure is generated in the combustion eham er (25), and from the latter flows into the compressing gasometer (5). From the compressing gasometer it flows into the res- 61V01I (47 being reduced to a degree required'for effectively operating an engine and in accordance with the'proportions and caacity of 'the engine supplled. Should the uid pressure, or the ressure ofv the kinetic larit in the explosions, or rapidity of explosions will not affect or fluctuate the ressure of the fluid inthe reservoir (47) an the fluid passing from the latter. to the engine will have a constant or uniform ressure with obvious advantages in the regulhractuation or stroke of the engine piston and'associated power transmitting instrumentalities.

It should be understood that in its broader aspect the invention comprehends the emplo ment not only of the various means described, but of equivalent means for performing the recited functions. While the arrangement shown is thought, at the present time, to be preferable, it is desired to reserve the right to effect such modifications and variations thereof as may come fairly Within the scope of the a pended claims.
